【Abstract】 In this paper,firstly,the local well-posedness of the Cauchy problem for the equation is established.Then for the equation with negative parameter nonlinearity,the global existence of solution is proved according to the energy equation and Bore-Cantelli lemma.Finally,for the equation with positive parameter nonlinearity,the solution is proved to blow up with some initial data according to the mass equation.The results obtained in this paper improve some others.更多还原
